Definitions

  • the present disclosure relates to a surgical suturing needle for suturing cutaneous and subcutaneous tissue, and in particular, relates to a surgical needle including a blunt needle end for minimizing undesired or inadvertent penetration of tissue while also possessing cutting edges extending from the blunt needle end to provide penetration capabilities comparable to conventional pointed surgical needles.
  • Suturing needles for applying sutures, or stitches, by hand in cutaneous and subcutaneous tissue are well known in the art.
  • the suturing needles are used to close wounds or adjoin adjacent tissue, often at the conclusion of a surgical procedure.
  • Suturing needles are usually made from a cut blank of material such as stainless steel. The cut blank is
  • the shaft generally includes a shaft, a rear end portion with an aperture or channel to secure a suture thread and a needle head at a front end portion for puncturing skin and passing through tissue.
  • needle head typically incorporates a sharpened needle tip at its distal end and cutting edges.
  • the needle tip may be of a tapered configuration.
  • Straight and curved needles including multiple curved configurations are also known in the art.
  • suture needles typically incorporate an extremely sharpened needle end. Sharper needles require less force to penetrate tissue and thus cause less tissue trauma. In addition, a sharper needle reduces fatigue on the needle itself, making it less likely to bend or
  • Needle sharpness is typically defined in terms of “penetration force” ⁇ the force necessary for a needle to puncture, or penetrate, the tissue.
  • the penetration force is primarily determined by the design and sharpness of the needle point and the cutting edges formed on the needle head. Needle sharpness is also affected by drag force on the needle as it travels through the tissue. The drag force also depends upon the design and sharpness of the needle, and
  • blunt surgical needles have been proposed. These surgical needles are generally of the taper-point design gradually tapering to a blunt needle end. However, these blunt surgical needles
  • taper point needles are devoid of cutting edges which detract from their usefulness in suturing tissue where relatively high penetration and drag forces are required to accomplish each needle
  • the surgical needle includes a needle body including leading and trailing ends and defining a longitudinal axis, a needle tip disposed adjacent the leading end of the needle body and having a blunt outer surface defining an arcuate configuration and at least one cutting edge extending from the needle tip toward the trailing end of the needle body.
  • the needle tip defines a circular cross-sectional dimension and may define a general spherical configuration.
  • the needle tip may define a general elliptical cross-sectional dimension.
  • the needle body includes a plurality (e.g., at least four) of cutting edges extending from the needle tip toward the needle body. Planar surface portions are disposed between adjacent cutting edges.
  • the needle body includes concave surface portions disposed between and forming the cutting edges.
  • the needle body preferably defines an outer extent adjacent leading ends of the
  • the leading ends of the cutting edges do not extend beyond the periphery of the needle tip. This feature significantly reduces the potential of tissue snagging on the leading ends of the cutting edges during a pass through tissue.
  • the outer extent of the needle body inclusive of the leading ends may be greater than an outer
  • the surgical needle includes a needle body defining leading and trailing ends, a general spherical region disposed adjacent the leading end of
  • the needle body and having a blunt outer surface, and a plurality of cutting edges extending from the spherical region toward the trailing end of the needle body.
  • FIG. 1 is a side elevational view of the surgical needle in accordance with the principles of the present disclosure
  • FIG. 2 is a side plan view of the needle end of the surgical needle of FIG. 1
  • FIG. 3 is an axial view of the needle end
  • FIG. 4 is a cross-sectional view of the needle end of the surgical needle taken along the lines 4-4 of FIG. 2
  • FIG. 5 is a cross-sectional view similar to FIG. 4 illustrating an alternate embodiment of the needle end
  • FIG. 6 is a cross-sectional view of the needle end of the surgical needle taken
  • FIG. 7 is a side plan view of another alternate embodiment of the surgical needle
  • FIG. 8 is an axial view of an alternative embodiment of the surgical needle of FIG. 1.
  • the surgical needle 10 of the present disclosure is a surgical needle 10 of the present disclosure.
  • Surgical needle 10 includes elongated needle body 12 havmg rear or trailing end 14 and forward or leading needle end 16. Needle body 12 is curved along its length through an arc "G" ranging from about 90° to about 180°. Narious angles of curvature are also envisioned. It is also contemplated that needle body 12 may be straight. As depicted in FIG. 2, needle body 12 defines longitudinal axis "y" which extends along the length of needle body 12.
  • trailing end 14 of needle body 12 defines a circular channel 20 (shown in phantom) dimensioned for reception of a suture end of a suture 100.
  • Channel 20 is closed about the suture end through conventional swaging or crimping processes to secure the suture 100 to elongated needle body 12. The dimensioning of channel 20
  • trailing end 14 may be selected to provide for permanent (non-detachable) or detachable
  • Channel 20 may be formed with a conventional laser drilling process or the like. It is further envisioned that trailing end 14 may be provided with an open u-shaped channel, an eyelet etc. for receiving the suture end.
  • Adhesive suture attachment methodologies are also envisioned where trailing end 14 is devoid of an opening or channel.
  • Needled end 16 includes needle tip 22, which in a preferred embodiment, defines a bulbous or spherical configuration having an arcuate outer surface 24. This spherical
  • Needle tip 22 may be in the form of a true spherical portion having a circular cross-section (FIG. 4) or alternatively may be an ellipsoid with an elliptical cross-section (FIG. 5).
  • An elliptical arrangement may be desired in instances where a reduced needle profile is required to, e.g., minimize the penetration force associated with entering
  • Needle tip 22 is devoid of any sharpened edges and/or planar surfaces which would otherwise undesirably alter the blunt characteristic and functionality of the
  • Needle body 12 further includes a plurality of cutting edges 26 which extend from
  • cutting edges 26 are provided, however, more or less than four cutting edges 26 are also contemplated. Cutting edges
  • Cutting edges 26 extend in a general longitudinal direction relative to longitudinal axis "y" and terminate at an intermediate portion 28 of needle body 12. Cutting edges 26 gradually taper outwardly toward trailing end 14 at an angle ranging from about 1° to about 10° relative to the longitudinal axis.
  • Cutting edges 26 are preferably triangular in cross-section as depicted in FIG. 6.
  • Cutting edges 26 define an effective lateral or radial extent at their leading ends 30 adjacent needle tip 22 substantially equivalent to the radial extent, i.e., diameter of needle tip 22. In particular, leading ends 30 of cutting edges 26 do not extend radially beyond the periphery, of
  • cutting edges 26 may be dimensioned to extend beyond the diameter of needle tip as depicted in the embodiment of FIG. 7.
  • needle body 12 further includes planar surfaces 32 which are disposed between cutting edges 26.
  • needle body 12 may incorporate concave surfaces 34.
  • Concave surfaces 34 may be formed through a conventional grinding process, e.g., a hollow grinding process, to extend between and define cutting edges 26. Concave surfaces 34 advantageously reduce required
  • Preferred materials include stainless steel such as series "300" stainless steels, which typically have tensile strengths of between 325,000-350,000 lbs/in.sup.2, attain their high strength from undergoing cold working as the material is converted from an ingot to wire of the desired diameter. "400" series stainless steel materials may also be utilized to form needle 10. Titanium, titanium alloys, biocompatible plastics are also envisioned.
  • Surgical needle 10 is manufactured through conventional cutting, coining, grinding
  • a lubricious coating such as silicon may be applied to needle body to further enhance penetration and drag characteristics.
  • Sutures for attachment to surgical needle 10 include silk, nylon, linen, cotton, polyester, polypropylene, stainless steel, natural material such as catgut, synthetic polymers having glycolic acid ester linkages subject to hydrolytic degradation to non-toxic tissue compatible absorbable components, including polyglycolic acid.
  • the sutures may be monofilamentary or braided, absorbable or non-absorbable.
